GEORGE LAKEY – Many assume that polarization is a barrier to making change. They observe more shouting and less listening, more drama and less reflection, and an escalation at the extremes. They note that mass media journalists have less time to cover the range of activist initiatives, which are therefore drowned out by the shouting. From coast to coast activists asked me: Does this condition leave us stuck? My answer included both good news and bad news. Most people wanted the latter first.

ROBERT C. KOEHLER – There’s a bigger problem embedded in the social order than our lack of effective gun laws, and I hope the movement that emerges out of the Parkland massacre makes the leap beyond anger and single-issue politics. The nation’s weak gun laws — the easy availability of AR-15 assault rifles — are, in fact, a symptom of the general cheapening of human life in American society, which is reflected in the nation’s ever-expanding obsession with war and a military budget the size of Godzilla. War always has a way of coming home.

NORMAN SOLOMON – Movie critics are already hailing “The Post,” directed by Steven Spielberg and starring Meryl Streep as Washington Post publisher Katharine Graham. Millions of people will see the film in early winter. But the real-life political story of Graham and her newspaper is not a narrative that’s headed to the multiplexes.

WINSLOW MYERS – It is long past time for us to recognize that the greater enemy is not someone in another country shouting threats, but the weapons themselves. On the basis of this shared truth, new relationships among adversaries can flourish that will allow reciprocal reduction and elimination. Nature within her inmost self divides, and science has unleashed this process on earth as the mighty power of fission, setting before us life or death choices. It is not too late to restrain the rise of the machines we ourselves have created, and choose life.

COLIN BEAVAN – Some years ago, the communications psychologist John Marshall Roberts said at a talk I attended that there are three ways of converting people to a cause: by threat of force, by intellectual argument, and by inspiration. The most effective of these methods, Roberts said, is aligning communication about your cause with the most deeply-held values and aspirations of your friends, relatives, neighbors, and fellow citizens. To get people’s total, lasting, and unwavering support, in other words, we should try neither to cajole them judgmentally nor convince them forcefully. We should inspire them toward a vision that they—not we—can really care about.

MEL GURTOV – North Korea is on a military tear. How and when any of the weapons the North claims to have might actually be operational is open to speculation. What does seem clear is that Kim Jong-un is pressing his weapons specialists to produce a reliable deterrent that will force the issue of direct talks with the U.S.

ANDREW J. BACEVICH – Policy intellectuals — eggheads presuming to instruct the mere mortals who actually run for office — are a blight on the republic. Like some invasive species, they infest present-day Washington, where their presence strangles common sense and has brought to the verge of extinction the simple ability to perceive reality. A benign appearance — well-dressed types testifying before Congress, pontificating in print and on TV, or even filling key positions in the executive branch — belies a malign impact. They are like Asian carp let loose in the Great Lakes.

TOM ENGELHARDT – The United States has been at war—major boots-on-the-ground conflicts and minor interventions, firefights, airstrikes, drone assassination campaigns, occupations, special ops raids, proxy conflicts and covert actions—nearly nonstop since the Vietnam War began. That’s more than half a century of experience with war, American-style, and yet few in our world bother to draw the obvious conclusions. Given the historical record, those conclusions should be staring us in the face. They are, however, the words that can’t be said in a country committed to a military-first approach to the world, a continual build-up of its forces, an emphasis on pioneering work in the development and deployment of the latest destructive technology, and a repetitious cycling through styles of war from full-scale invasions and occupations to counterinsurgency, proxy wars, and back again.

JOHN LAFORGE – After so much blood and destruction in Afghanistan, a lot of people dream of Secretary of State John Kerry reviving his monumental 1971 question, “How do you ask a man to be the last man to die for a mistake?”

DAVID SWANSON – Jody Williams’ new book is called My Name Is Jody Williams: A Vermont Girl’s Winding Path to the Nobel Peace Prize, and it’s a remarkable story by a remarkable person. It’s also a very well-told autobiography, including in the early childhood chapters in which there are few hints of the activism to come. One could read this book and come away thinking “Anyone really could win the Nobel Peace Prize.”
